Enter the (collagen) matrix

Nearly a year ago, I posted about the minor periodontal surgery I had to deal with the receding gumline on my lower front teeth. I said there might be a second procedure to graft gum tissue from my palate into the receded area (to protect the roots of the front teeth), but I was hoping that wouldn’t be necessary. It soon enough became evident that it would be necessary, but I put it off as long as I could, until finally the peridontist’s office called me last month to schedule the procedure, which was done yesterday.

Turns out that putting it off worked out well, though, because in the interim, the doctor began doing a new version of the procedure which he offered me as an alternative. Instead of taking gum tissue from my upper palate, he could implant an artificial graft, basically just a scaffold of collagen (porcine in origin — I guess from pig hooves or something, but carefully purified and sterilized) that my own fibroblasts would grow into, forming new gum tissue to replace what was lost, with the collagen eventually breaking down and being “resorbed” into my body. So instead of taking existing gum tissue and moving it elsewhere, it’s enabling me to grow new gum tissue where the old tissue was lost.

The high-tech nature of the procedure appealed to me, as did the fact that it would simplify the operation and let me avoid the cutting into my upper palate. But I still took care to ask questions and read the documentation about the graft. There didn’t seem to be any significant drawbacks and there were definite advantages, so I agreed to the new procedure. It wasn’t very pleasant getting Novocaine stuck into my gums (though he used the sonic wand that temporarily numbed my nerves to ease the pain of the needle going in) and having him go in and pull things back and stitch things in, but it was easier than it would’ve been before the new grafts became available.

And now it’s the same drill as last time — ice packs and ibuprofen, soft foods and nothing hot for the first day or so, then no biting with the front teeth for about a month. Last time I found I was able to get by with a pretty normal diet so long as I cut things into small pieces, but I think I’ll still be having fewer sandwiches and more pasta salad for a while.

And within a couple of months or so, as long as I’m careful to avoid putting too much pressure on the area and crushing the collagen matrix so the cells can’t grow into it, I’ll have a nice new intact gumline there. I wish there were other parts of my body I could regenerate like that. Hopefully, by the time I need to, medical science will have made it possible.
